1 objects around us are composed of many mixtures. If the mixture were found. Mixture resembles meat looked to see whether there is substance to coexist more than one species, such as water in the canal, salt, pepper, dip fruit such as mixtures of these compounds, mixed, some looked noticed like that exists. only one type of connection, such as water, salt water, perfumed talcum powder so that the mixture of these. Homogeneous Materials 2 Criteria for classification as a category of several criteria such as the presence of substances, the nature of the substance. Or particle size distribution of the substance or substances using the different materials will have different categories with three. In recognition of the size of the particles. Find the right material for screening compounds by particles of different sizes, such as filter paper bags cellos defenseman on four substances that are larger than 10-4 cm diffusion in the liquid. It is huge, it will be clearly visible and sedimentation, which can not easily pass through the filter paper and cellos in Frankfurt. These mixtures classified as suspended solids. Some of the mixture through a filter paper was all but over cellos defenseman. Explained that the mixture has a particle size of less than 10-4 cm but larger than 10-7 cm spread on five. This mixture is a colloidal The mixture has a particle size less than 10-7 cm spread. Through the filter paper and cellos to provide a solution that defenseman when beaming through mud, water, milk, mix oil and water mixed with fresh water, found a sweet spot to see clearly. The muddy water is opaque Water and sweet red transparent. We see the beam in the milk. Because the particles in milk to make light scattering in all directions to see the beam. And the phenomenon is seen as a beam of light is called a colloid. Tin Tyndall phenomenon in everyday life we are exposed to on a regular basis colloid. Such as salad oil There will be a mixture of water, oil, egg yolk and water, especially if we put the two types of oil have different densities are not homogeneous. To separate out clearly But if you put the egg yolk mixture into it. Egg yolks will make it to and fro as the water, oil and egg yolk together in a homogeneous emulsion. This is a type of colloidal The yolk provides water and oil as well as homogeneous as possible. Emulsifier power supplier, another example of a colloid is seen as a beam of light cars. It is caused by the air in front of a car filled with dust. When light is incident from the lamp compartment with small particles of dust. The blowing in front of the car The scattering of light The beam is visible This is called colloidal particles floating solid.
